Petunia plant named ‘Balrufimvein’

ABSTRACT

A new and distinct Petunia plant named ‘Balrufimvein’ characterized by its double purple-colored flowers with darker purple veins, dark green-colored leaves, and a mounded and trailing growth habit.

Latin name of the genus and species of plant claimed: Petunia×hybrida.

Variety denomination: ‘Balrufimvein’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Double Petunia plant botanically known as Petunia×hybrida and hereinafter referred to by the cultivar name ‘Balrufimvein’.

The new petunia was developed by the inventor through a controlled breeding program during October 2000 at Arroyo Grande, Calif. The objective of the breeding program was the development of Petunia cultivars with large, fully double flowers of unique colors and vigorous mounded and trailing growth habits.

The female parent of ‘Balrufimvein’ was the proprietary Petunia×hybrida breeding selection designated 539A, not patented, which exhibits a semi-trailing habit, dark green-colored foliage, and single pink/white bi-color flowers. The male parent of ‘Balrufimvein’ was the Petunia cultivar Pricilla (not patented) which exhibits a semi-trailing habit, dark green-colored foliage, and fragrant, double, pale purple-colored flowers with darker purple-colored veins. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during March 2001 in a controlled environment at Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings taken since March 2001 at Arroyo Grande, Calif. and West Chicago, Ill., has demonstrated that the new cultivar reproduces true to type with all the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length without, however, any variation in genotype.

It was repeatedly found that the cultivar of the present invention:

1 Exhibits double purple-colored flowers with distinct darker purple venation.

2 Forms dark green-colored foliage.

3 Exhibits a good basal branching character.

4 Exhibits a vigorous mounded and trailing growth habit.

Plants of the new cultivar differ from plants of the female patent primarily in flower form and from the male parent primarily in flower color.

Of the many Petunia cultivars known to the inventor, the most similar to ‘Balrufimvein’ is the cultivar Kirimaji Double Purple (U.S. Plant Pat. No. 14,283). However, in side-by-side comparisons, flowers of the new cultivar are a lighter purple color than flowers of the cultivar Kirimaji Double Purple.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the color of ‘Balrufimvein’. The plants were grown for 12 weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 1995 edition, except where color terms of ordinary significance are used. The color values were determined on Oct. 15, 2003. The readings were taken between 1:00 and 3:00 p.m. under natural daylight conditions.

Plants used for the following descriptions and measurements were grown in 10 cm pots for 12 weeks from rooted cuttings. The plants were produced from cuttings taken from stock plants and grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown using a soilless growth medium with greenhouse temperatures maintained at approximately 55°-75° F. (13°-24° C.) during the day and approximately 50°-60° F. (10°-16° C.) during the night. Greenhouse light levels of 5,000-8,000 footcandles were maintained during the day.
